Overload
The converter has detected the onset of an
internal overload condition. This is usually
due either to exceptionally high traffic rates
or failure conditions causing additional
invocation of maintenance procedures.
During overload the converter will continue
to operate as normal. Should the condition
occur on a frequent basis (e.g.: during the
busy hour every day) the condition should be
reported to DataKinetics.
0 0 SYS
33
Sync failure
None of the PCM ports that have been
configured as possible clock sources
contain a valid PCM signal. Under these
conditions the converter will generate
synchronisation using a local oscillator.
0 0 PCM
34
New sync source
The converter has selected a new PCM as
the clock synchronisation source.

System restart req
The user has changed configuration
parameters that require the system to be
restarted before they can take effect. The
alarm will persist until the system is
restarted.

RDC failure
Failure of communication with a remote data
centre. Usually due to incorrect configuration
(IP address, username or password),
connectivity fault or inactive equipment at
the remote end.
RDC 0
SIG
41
All RDC fail
Failure of communication with all remote
data centres. Continuous records will be
written to hard disk or discarded as
appropriate. Periodic report data will be
discarded. It is important to note that on
failure of all RDCs any billing records (if
enabled) will be written to local hard disk
which has a limited capacity.
